CONVEYING are effective for long , straight and flat distances , they become costly and inefficient in complex terrain or extended runs with steep gradients . Pietila : “ Conventional belt conveyors are limited to gradients that avoid risk of material rollback . This often requires significant land grading or rerouting of conveyors , depending on the terrain . In contrast , Railveyor can manage gradients of 20-30 %, facilitating more direct and cost-effective routing while limiting expensive infrastructure requirements .”
An important benefit of the tight turning radius is that it eliminates the need for transfer points . Apart from avoiding the considerable costs of chute infrastructure at transfer points , mines also reduce their risk of disrupting material flow when there are blockages , heavy wear or other issues at these points .
“ Railveyor systems also demand less infrastructure to install , and are readily movable and adaptable . Unlike the graded roads and extensive ballast , sleeper and drainage elements demanded by traditional rail , for instance , Railveyor relies on light rail that can be installed on uneven terrain without the need for precisely graded surfaces . This means lower installation and maintenance costs as there are reduced earthworks , construction and road repairs necessary .”
A perennial risk to mines is the unplanned downtime from a conveyor belt or component
failure – potentially taking days to source and replace . By comparison , Railveyor ’ s modular design and fewer moving parts allow a train or

A large operation utilising three discharge loops to efficiently haul material from underground using the Railveyor system
car needing attention to be removed from the track for maintenance while the rest of the system continues to operate .
Leveraging the energy efficiency of steel wheels on steel tracks , Railveyor goes further by using electrically powered drive stations to ensure consistent energy distribution along the route . These motors power drive wheels or linear drive systems that propel the lightweight rail cars forward . During downhill or decelerating movements , the system employs regenerative
